AS14559 — BRTCC

AS14559 announces 2 IPv4 prefixes covering 8,192 addresses and 0 IPv6 prefixes.

About this network

Two different addresses answer with the same hostname, and that hostname holds only three parts of an address.

What it's used for

• A rural telephone cooperative's internet network. 8,192 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Both blocks carry the netname BRTCC, registered to Ballard Rural Telephone Cooperative Corporation Inc.
• Two of six sampled addresses returned a name, and both answered the same: 67-216-112-brtc.net.
• The addresses queried were 67.216.119.255 and 67.216.123.254, neither of which matches the numbers in the name they returned.

Interesting

• A reverse name carrying three parts of an address rather than four identifies a block, not a host. Every address in the /20 answers with the base of the range, so a lookup tells you which allocation an address belongs to and nothing more. It satisfies the tools that insist on an answer without maintaining eight thousand records.
• The numbers in the name do not match either address queried, which will look like a misconfiguration to anyone checking that a name maps back to the address it came from. Some mail systems reject on exactly that test.
• The domain drops a letter from the netname, so the cooperative is BRTCC in the registry and brtc in DNS. Four letters fit a domain better than five.
• Two /20s, one netname, two neighbours: a cooperative with exactly what it needs and no history to explain.
